Which browser and OS are you using? I notice that behavior in Firefox on Mac, but not in Chrome on Mac. When I tested years ago in Chrome and Firefox on Linux, that definitely wasn't happening. In general, I've found a few inconsistent behaviors on how drag and drop is implemented across browsers and OSes, and possibly in different browser versions over time.
